During the G1 (gap 1) phase, cells grow continuously and prepare for DNA replication. During this phase, cells are metabolically active and copy essential organelles and biochemical molecules, such as proteins. In the subsequent S (synthesis) phase of interphase, cells duplicate their nuclear DNA...
G1 refers to the first gap of time in the cell cycle and G2 refers to gap number two. The other phases of the cell cycle, S and M, refer to the terms "synthesis" and "mitosis," respectively. Within the G1 phase, the subphases ...
G1 phaseis the growth phase, where cells are provisioned with metabolites while mostbiosynthesisoccurs. It is the longest phase of the cycle, but also the most variable in duration. Cells synthesize proteins and prepare forDNA replicationoccurring in S phase. DuringG2 phase, cells enhance thede...

G1 phase death in response to higher concentrations of the destabilizers was associated with complete loss of interphase microtubule structure. In contrast, HeLa cells were only susceptible in M phase regardless of drug type or concentration. These results represent an important advance in our ...
We have examined the ability of the yeasts Schizosaccharomyces pombe and Saccharomyces cerevisiae to enter a quiescent state through G1, S, G2, or M phase of the cell cycle. We monitored entry to a quiescent state by measuring two well known properties of quiescent cells, i.e., long-term...
Further decondensation in later G1 and early S phase results in predominantly 60-80-nm chromonema fibers that can be traced up to 2-3 microns in length as discrete fibers. Abrupt transitions in diameter from 100-130 to 60-80 nm along individual fibers are suggestive of coiling of the 60...
4) S Phase S期 1. The rRNA synthesis in the nucleolus continued actively throughout the interphase, while in nucleoplasm hnRNA was transcribed at low levels in S phase and actively in G 2 phase. 结果表明 :在整个间期核仁中的rRNA都在活跃转录 ;核质中hnRNA的转录呈逐渐上升趋势 ,早S期转录...
Few large pri-FCs coexisted with numerous tiny sec-FCs in the nucleolus of HeLa cells in G2 phase. Based on the results of our observation, we suggest here a model of the dynamic change and the process of derivation of FC and DFC through interphase. 展开 关键词: Pri‐FC and pri‐DFC...
The ability of synchronized Ehrlich ascites tumour cells to repair PLD was measured by introducing delays in their progression through the cell cycle either in the same phase as that where the irradiation was given or in a subsequent phase. Cells were incubated for this purpose either in balanced...
